Reject Human. Become Demon. [Book 3 Finished! Book 1 Stubbed.]

Book 1: Available on Amazon! [In a world of powerful monsters, dangerous sapients, and Angelic Overlords, Haell the Human will become a Demon and slay them all!] All I ever wanted was to become a demon. And then I died. But beyond that death I found a whole new world, one which may finally allow me to achieve my dreams! There was magic here, Mutations, and creatures only seen in fantasy! It was a land dominated by Angelic Overlords and their shepherd pawns, but not even they could ruin my sheer enthusiasm. For my parents were amazing, the world shone brightly in wonder, and the power that I so craved was now within reach!  I just had to reach for it. I was ready to toil. And though my tears may run dry, and so would my blood be spilled, my will shall forever remain unbroken. I will claw my way to power. I will become a demon. No matter the cost. ---What To Expect!--- --A Main Character that chooses VIOLENCE. --Wish fulfillment parents that love and care for you no matter what. (Shh. It's fine. Let it all out.) --A wondrous and complex magic system, and an MC who is absolutely excited and overjoyed to explore it! (But not to the point that it's overwhelming, don't worry.) --It's not slow-paced. Months and even years frequently pass between and within singular chapters. The MC just gets a chance to train first before all the craziness. The world isn't trying to kill a random 5 y/o child. --Haell won't immediately become a demon, but it won't take her forever to succeed either. Don't worry about it! --NON-HUMANOID SAPIENTS. ---Additional Information--- --Cover Art made by @FuwaFuru -- Masterlist of Content Warnings for Every Chapter
